We put the first one in at our shop Friday. Went into a TL. It is truly an impressive piece and somewhat legitamizes JBL as a player. There is a ridiculous amount of technology built into this piece. And when it is mated with nice equipment and tuned properly, it is nothing short of incredible. We still have to do a few more installs with it but I can tell you that I agree with it being better than the Alpine Imprint piece (I never liked it-never happy with the results for the money).
